As Representatives of the

Underwriters named in

Schedule II hereto

Ladies and Gentlemen:

Hess Corporation, a Delaware corporation (the “Company”), proposes to issue and sell to the underwriters named in Schedule II hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), the principal amount of its debt securities identified in Schedule I hereto (the “Securities”), to be issued under the indenture specified in Schedule I hereto (the “Indenture”) between the Company and the Trustee identified in such Schedule (the “Trustee”). If the firm or firms listed in Schedule II hereto include only the firm or firms listed in Schedule I hereto, then the terms “Underwriters” and “Representatives”, as used herein, shall each be deemed to refer to such firm or firms.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), an “automatic shelf registration statement” as defined under Rule 405 under the Securities Act on

Form S-3 (File No. 333-179744) relating to certain securities to be issued from time to time by the Company. The base prospectus filed as part of such registration statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement, is hereinafter called the “Basic Prospectus”. Any preliminary prospectus (including any preliminary prospectus supplement) relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act is hereinafter called a “Preliminary Prospectus”. The various parts of such registration statement, including all exhibits thereto but excluding Form T-1 and including any prospectus supplement relating to the Securities that is filed with the Commission and deemed by virtue of Rule 430B to be part of such registration statement, each as amended at the time such part of the registration statement became effective, are hereinafter collectively called the “Registration Statement”. The Basic Prospectus, as amended and supplemented immediately prior to the Applicable Time (as defined in Section 4(c) hereof), is hereinafter called the “Pricing Prospectus”. The form of the final prospectus relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act in accordance with Section 5(a) hereof is hereinafter called the “Prospectus”. Any reference herein to the Basic Prospectus, the Pricing Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the date of such prospectus. Any reference to any amendment or supplement to the Basic Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any post-effective amendment to the Registration Statement, any prospectus supplement relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act and any documents filed under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”), and incorporated therein, in each case after the date of the Basic Prospectus, such Preliminary Prospectus or the Prospectus, as the case may be. Any reference to any amendment or supplement to the Registration Statement shall be deemed to refer to and include any documents filed under the Exchange Act after the effective date of the Registration Statement that is incorporated by reference in the Registration Statement. Any “issuer free writing prospectus” as defined in Rule 433 under the Securities Act relating to the Securities is hereinafter called an “Issuer Free Writing Prospectus”.

The Company hereby agrees with the Underwriters as follows:

1. The Company agrees to issue and sell the Securities to the several Underwriters as hereinafter provided, and each Underwriter, on the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees to purchase, severally and not jointly, from the Company the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule II hereto at the purchase price set forth in Schedule I hereto plus accrued interest, if any, from the date specified in Schedule I hereto to the date of payment and delivery.

2

2. The Company understands that the several Underwriters intend (i) to make a public offering of their respective portions of the Securities and (ii) initially to offer the Securities upon the terms set forth in the Pricing Disclosure Package (as defined in Section 4(c) hereof). Each of Banca IMI S.p.A. (Intesa) and Standard Chartered Bank represents that it will not effect any offers or sales of any Securities in the United States unless it is through one or more U.S. registered broker-dealers as permitted by the regulations of FINRA.

3. Payment for the Securities shall be made by wire transfer in immediately available funds to the account specified by the Company to the Representatives, no later than noon the Business Day (as defined below) prior to the Closing Date (as defined below), on the date and at the time and place set forth in Schedule I hereto (or at such other time and place on the same or such other date, not later than the fifth Business Day thereafter, as you and the Company may agree in writing). As used herein, the term “Business Day” means any day other than a day on which banks are permitted or required to be closed in New York City. The time and date of such payment and delivery with respect to the Securities are referred to herein as the “Closing Date”.

Payment for the Securities shall be made against delivery to the nominee of The Depository Trust Company for the respective accounts of the several Underwriters of the Securities of one or more global notes (the “Global Note”) representing the Securities, with any transfer taxes payable in connection with the transfer to the Underwriters of the Securities duly paid by the Company. The Global Note will be made available for inspection by the Representatives at the office of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, New York 10017, not later than 1:00 P.M., New York City time, on the Business Day prior to the Closing Date.

(f) White & Case LLP, counsel for the Company, shall have furnished to you their written opinion, dated the Closing Date, in form and substance satisfactory to you, to the effect that:

(i) the Company has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties, or conducts any business, so as to require such qualification, other than where the failure to be so qualified or in good standing would not have a material adverse effect on the Company and its subsidiaries taken as a whole;

(ii) each of the Significant Subsidiaries has been duly incorporated and is validly existing as a corporation under the laws of its jurisdiction of incorporation with corporate power and authority to own its properties and conduct its business as described in the Prospectus and has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties, or conducts any business, so as to require such qualification, other than where the failure to be so qualified and in good standing would not have a material adverse effect on the Company and its subsidiaries taken as a whole; and all of the issued shares of capital stock of each such subsidiary have been duly and validly authorized and issued, are fully paid and non-assessable, and (except in the case of foreign subsidiaries, for directors’ qualifying shares) are owned directly or indirectly by the Company, free and clear of all liens, encumbrances, equities or claims;

18

(iii) other than as set forth or contemplated in the Prospectus, there are no legal or governmental investigations, actions, suits or proceedings pending against or, to the best of such counsel’s knowledge, threatened against or affecting the Company or any of its subsidiaries or any of their respective properties or to which the Company or any of its subsidiaries is or may be a party or to which any property of the Company or its subsidiaries is or may be the subject which could individually or in the aggregate reasonably be expected to have a material adverse effect on the general affairs, business, prospects, management, financial position, stockholders’ equity or results of operations of the Company and its subsidiaries taken as a whole; to the best of such counsel’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others; and such counsel does not know of any statutes, regulations, contracts or other documents required to be filed as an exhibit to the Registration Statement or required to be described in the Registration Statement or the Prospectus which are not filed or described as required;

(iv) neither the Company nor any of its Significant Subsidiaries is, or with the giving of notice or lapse of time or both would be, in violation of or in default under, (x) its Certificate of Incorporation or By-Laws (or similar constitutive documents) or (y) any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel to which the Company or any of its Significant Subsidiaries is a party or by which it or any of them or any of their respective properties is bound, except, in the case of this clause (y), for violations and defaults which individually and in the aggregate are not material to the Company and its subsidiaries taken as a whole; the issue and sale of the Securities and the performance by the Company of its obligations under the Securities, the Indenture and this Agreement and the consummation by it of the transactions herein and therein contemplated will not (A) conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to such counsel to which the Company or any of the Significant Subsidiaries is a party or by which the Company or any of the Significant Subsidiaries is bound or to which any of the property or assets of the Company or any of the Significant Subsidiaries is subject, except for such conflicts, breaches or defaults as would not have a material

19

adverse effect on the Company and its subsidiaries, taken as a whole, and (B) result in any violation of (x) the provisions of the Certificate of Incorporation or the By-Laws of the Company or (y) any applicable law or statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company, its subsidiaries or any of their respective properties except, in the case of this clause (y), for violations that would not have a material adverse effect on the Company and its subsidiaries, taken as a whole;

(v) the statements in the Prospectus incorporated by reference from Item 3 of Part 1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 and as such statements have been amended or supplemented by the Company’s subsequent reports filed on Form 10-Q or Form 8-K, insofar as such statements constitute a summary of the legal matters, documents or proceedings referred to therein, fairly present in all material respects the information called for with respect to such legal matters, documents or proceedings; and

(vi) such counsel is of the opinion that each document incorporated by reference in the Registration Statement and the Prospectus as amended or supplemented (other than the financial statements and related schedules therein, as to which such counsel need express no opinion) complied as to form when filed with the Commission in all material respects with the Exchange Act and the rules and regulations of the Commission thereunder.

In rendering such opinions, White & Case LLP and Mr. Goodell may rely (A) as to matters involving the application of laws other than the laws of the United States and the States of New York and Delaware, to the extent such counsel deem proper and to the extent specified in such opinion, if at all, upon an opinion or opinions (in form and substance reasonably satisfactory to Underwriters’ counsel) of other counsel reasonably acceptable to the Underwriters’ counsel, familiar with the applicable laws; (B) as to matters of fact, to the extent such counsel deem proper, on certificates of responsible officers of the Company and certificates or other written statements of officials of jurisdictions having custody of documents respecting the corporate existence or good standing of the Company. The opinion of each such counsel shall state that the opinion of any such other counsel upon which they relied is in form satisfactory to such counsel and, in such counsel’s opinion, the Underwriters and they are justified in relying thereon. With respect to the matters to be covered in subparagraph (viii) of paragraph (f) above White & Case LLP may state that their opinion and belief is based upon their participation in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus and any amendment or supplement thereto (other than the documents incorporated by reference therein) and review and discussion of the contents thereof (including the documents incorporated by reference therein) but is without independent check or verification except as specified.

20

The opinions of White & Case LLP and Mr. Goodell described above shall be rendered to the Underwriters at the request of the Company and shall so state therein.

(h) On the date hereof and on the Closing Date, Ernst & Young LLP shall have furnished to you letters, dated each such date, in form and substance satisfactory to you, containing statements and information of the type customarily included in accountants “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement, the Pricing Prospectus and the Prospectus.

(i) On the date hereof and on the Closing Date, DeGolyer and MacNaughton shall have furnished to you letters, dated each such date, in form and substance satisfactory to you, containing statements and information of the type customarily included in reserve engineers “comfort letters” to underwriters with respect to reserve information contained in the Registration Statement, the Pricing Prospectus and the Prospectus.

(j) You shall have received on and as of the Closing Date an opinion of Davis Polk & Wardwell LLP, counsel to the Underwriters, with respect to the validity of the Indenture and the Securities, the Registration Statement, the Prospectus and other related matters as you may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters.

(k) On or prior to the Closing Date, the Company shall have furnished to the Representatives such further certificates and documents as the Representatives shall reasonably request.

8. (a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, the reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted), caused by (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or caused by (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements

21

therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus.

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Person”) in writing, and the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.

(d) It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to one local counsel in each jurisdiction where a proceeding is pending) for all such Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Underwriters and such control persons of

22

Underwriters shall be designated in writing by the Representatives, and any such separate firm for the Company, its directors, its officers who sign the Registration Statement and such control persons of the Company or authorized representatives shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel as contemplated by the first sentence of this Section 8(d), the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (i) includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Person.

(e) If the indemnification provided for in Section 8(a) or 8(b) is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) if the allocation provided by clause 8(e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(e)(i) above but also the relative fault of the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by the Company

23

and the total underwriting discounts and the commissions received by the Underwriters bear to the aggregate public offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of the Securities set forth opposite their names in Schedule II hereto, and not joint. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or by or on behalf of the Company, its officers or directors or any other person controlling the Company and (iii) acceptance of and payment for any of the Securities.

24

9. Notwithstanding anything herein contained, this Agreement may be terminated in the absolute discretion of the Representatives, by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange LLC, NYSE Amex LLC or The Nasdaq Stock Market LLC, (ii) trading of any securities of or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States, or (iv) there shall have occurred any outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war or (v) the occurrence of any other calamity or crisis or any change in financial or economic conditions in or affecting the United States, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representatives, is material and adverse and which, in the judgment of the Representatives, makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus.

10. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Securities which it or they have agreed to purchase under this Agreement on such date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such principal amount of Securities without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

25

11. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company agrees to reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and expenses of their outside counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering of Securities contemplated hereunder.

12. This Agreement shall inure to the benefit of and be binding upon the Company, the Underwriters, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

13. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

14. Any action by the Underwriters hereunder may be taken by the Representatives alone on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: High Grade Syndicate Desk; Morgan Stanley & Co. LLC, 1585 Broadway, New York, NY 10036,

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

15. This Agreement may be signed in counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument.

16. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to the conflicts of laws provisions thereof.
